AI Technical Summary

Technical Problem

In multi-needle sewing machines, the needle and thread are prone to bending and tangling when moving, and insufficient tension causes the needle and thread to become loose, affecting the sewing effect.

Method used

Design a thread pressing mechanism for a multi-needle machine, including a mounting plate, an adjustable pressing plate, and a rotating plate. The rotating plate, in cooperation with rollers, provides a continuous pressing action to ensure that the needle thread remains straight during movement. The mechanism can also be adjusted to accommodate needle threads of different thicknesses.

Benefits of technology

It effectively prevents needle and thread from bending and tangling, ensures stable needle and thread movement, adapts to needle and thread of different thicknesses, expands the applicable range of the pressing device, and fixes the needle and thread when not in use.

Abstract

The utility model discloses a thread pressing mechanism for a multi-needle machine, which comprises a mounting plate, an adjustable pressing plate is arranged at the bottom of the mounting plate, pay-off grooves for placing needles and threads are uniformly formed in the bottom of the pressing plate, a rotatable rotating plate rotates at the top of the pressing plate, and a reset spring is arranged between the rotating plate and the pressing plate. Compared with the prior art, the device has the advantages that the rotating plate can be driven to rotate when the needle thread is driven to move along with the operation of the multi-needle machine, so that the needle thread can be continuously pressed when being pulled, the stability of the movement of the needle thread is ensured, and the service life of the needle thread is prolonged. And continuous pulling force is applied to the needle thread, so that the needle thread is always kept in a straightened state, the use of the multi-needle machine is ensured, the problem of winding caused by bending of the plurality of needle threads is avoided, and the plurality of rollers and the rotating plate can be integrally limited and adjusted.
